  • 1031 is ridiculously huge too. The NSA probably works on EB scales, which is “only” 1018 bytes. If you can get up to 1022 equally likely passwords you’re fine against dragnet, brute force-style attacks. (If you’re zombie Bin Laden and the NSA will stop for a whole year cracking your drive, and doesn’t have any shortcuts, maybe you need 1039 I guess)

    That being said, if more characters is no problem, go ahead and do that. I’m not saying more security for free is a bad thing.

    Which they tend to do a lot. Like, the moment a square root or trig function shows up.

    Even without it’s pretty easy to overflow a fraction stored the way you’re describing. x=1/(x*x+1) does it in log time. There’s really not a lot of situations where exact fractions work, but purely symbolic logic wouldn’t. Maybe none, IDK.

    Edit: I mean, I guess it’s all symbolic. What I’m trying to say is that if you’re at a level of detail where you can keep track of the size of denominators, native support for a type that hides them is counterproductive. It’s better to lay out your program in such a way that you just use small integers, which is guaranteed to be possible in that case.















  • Ah. Yes, things changed a lot over the next couple decades. The last anti-idpole people were just being purged right as I became aware of goings-on in the community. I’m glad it went that way instead of the other, and people of all sorts were in the room, but in the end the exact extent of acceptance became a new thing to fight over. Is furry stuff a fetish or a type of queer identity? Is vegetarianism anti-indigenous? Are poor, conservative white people potential converts, or something like Marx’s “petty bourgeoisie”? What about, like, Hindu traditionalists? These would all be good things to hash out, but polite debate is not valued.

    Man, I wish Lemmy had a follow user feature. It sounds like you went through some of the same stuff I did but in gen X times.

    Also, heads up that this instance is run by the Lemmy developers, who happen to be very active members of the far left. They can be ban-happy sometimes.
